If you for chance read my previous diary entry, I registered on GiveIt100 and documented with a video a changeset made each day in a different country.
I followed some basic criteria: each day in a different continent (counterclockwise order); if I missed a day I'd map in the same continent for two days; map in a country where I didn't map before.

So, straight from January 1st, I got to April 10th and in the last video I did a changeset in San Mateo, CA, where lives the developer of GiveIt100 (I previously mapped in USA, I know!).
